To all whom it may concern the straw carrier or shaker, and has its bottom Be it known that I, WILLIAM AGKERMAN, or flooring 01 set inclining from its outer end of Mansfield, county of Richland, State of inward, forming a return-chute, which serves Ohio, have invented certain new and useful to return the grain separated from the straw 5 Improvements in Grain-Separators, of which in the passage of the latter over it, and to dethe following is a full, clear, and exact descripposit the same upon the lower shaker or screen. tion, reference being bad to the accompanying Above this flooring d is arranged a series of drawings, making part of this specification, longitudinal strips, d, supported attheir outer in whichends by the end bar or plate, D, and at their 10 Figure 1 represents a vertical longitudinal innerends byatransversebar,D raised above section through a grain separating attachment the flooring, as shown, to permit the unobto thrashing-machines, or so much thereof as structed return of the grain.

The fingers of 5 to lfinge this extension to the lower shaker in one shaft overlap the succeeding shaft, those the position shown in the patent to Allonas of the last shaft,F overlapping the shaftF of referred to. This extension-pan is made in the the extension, (or the first, where more than form of along, shallow box or pan, open on top one is used.) By this arrangement the straw 50 and at its inner or receiving end, adjacent to is agitated by the fingers throughout its enmo tire passage over the carrier and the hinged extension. The side bars of the extension-pan, or the plates of the hinges connecting them with the straw-carrier, have toothed or ratchet-bars g pivoted to them, said bars engaging with pins or studs g on the carrier, as shown, for holding the extension-pan at any desired angle of adjustment. By this arrangement greater or less resistance is offered to the discharge of the straw, as may be necessary for effecting the thorough separation of the grain therefrom.

Other means may be employed for effecting the adjustment of the hinged extension, and a different arrangement may be made of the hinge or hinges connecting it with the strawcarrier or the lower shaker.

Parts of the machine not particularly described may be constructed and arranged in any usual or preferred manner.
